31 Prophet 12 Module Operation Manual Auxiliary Envelopes
Auxiliary Envelopes
The Prophet 12 has four, five-stage envelope generators. Two of them are dedi -
cated to the low-pass filter and VCA, but the other two can be routed to any of
the modulation destinations.
Note:
Actually, any of the envelopes can be routed to any destination—or
multiple destinations—using the modulation matrix. See
Modulation
on page
32 for more information.
See Low-Pass Filter on page 18 for an illustrated example of an envelope
generator.
Destination
—The parameter being modulated by the envelope. See Modulation
Destinations
on page 50 for a list of possible destinations.
Envelope Amount: -127...127
—Sets the amount of modulation from the
envelope to the chosen destination. The modulation amount can be positive or
negative, allowing for inverted envelope control.
Velocity
’
Envelope Amount: 0...127
—Enables keyboard velocity to modu-
late the e
nveloPe
a
mount
.
Delay: 0...127
—Sets a delay between the time the envelope is gated on and
when the Attack portion actually begins.
Attack:
0...127
—Sets the attack time of the envelope.
Decay: 0...127
—Sets the decay time of the envelope.
Sustain: 0...127
—Sets the sustain level of the envelope.
Release: 0...127
—Sets the release time of the envelope.
Repeat: Off, On
—When on, the Delay, Attack, and Decay segments of the
envelope repeat. Sustain still affects the level at which the Decay segment ends,
but—instead of sustaining at a fixed level while a note is gated on—Delay,
Attack, and Decay loop until the note is turned off. The Release segment begins
when the note is gated off, just as it does when Repeat is off. For an illustrated
example, see Low-Pass Filter on page 18.
